Abstract
Description
- This application is entitled to, and claims the benefit of, provisional application No. 60/326,174 filed 25 Apr. 2002.
- The present invention relates generally to the field of data communications, and, more specifically, to the performance, optimization, and configuration testing of wireless local area network access points.
- Many, including development engineers, network administrators, and network testing organizations, have occasion to test the performance of wireless local area networks. The accepted practice of testing wireless local area networks is to install numerous computers with wireless network capability, then associate, authenticate, and present requests for data to a wireless hardware device called an access point, sending and receiving data streams over a high frequency radio channel. This common practice is expensive, driven by the cost of the many computers, and is not easily configurable for the commonly needed variety of user population sizes and data traffic loads.
- The present invention, employing what is termed a load emulator, overcomes the considerable expense and inadequacies of the accepted practice of testing wireless local networks by emulating a programmable number of virtual stations, associating each virtual station with the access point, authenticating the user for security purposes, and transferring data designed to elicit performance parameters over a wireless link.
- The load emulator method and apparatus (or system) has many advantages over the accepted practice, providing variable and realistic network load conditions, allowing network builders to quickly determine the efficiency and capacity of an access point under test.
- Three components make up the load emulator test environment, 1) a computer to command test parameters and display results, 2) the load emulator, and 3) the wireless access point under test. With this configuration one can emulate from 1 to 255 virtual stations with realistic network addresses, network association procedures, user authentication processes, and transfer of data over the wireless network.
- From this test procedure, a variety of information is collected, analyzed and displayed. One can use this information to analyze the access point under test, make configuration adjustments to optimize overall performance, determine access point capacity, establish boundaries of the target user population size, conduct performance comparisons of network equipment manufacturers, and acquire other useful data and information.
- The objects, features, and advantages of the present invention will be apparent to the reader from the foregoing and the appended claims and as the ensuing detailed description and discussion proceeds in conjunction with the accompanying drawings.
- FIG. 1 is a block diagram illustrating a typical test environment embodying the principles of the present invention and comprising a load, emulator as disclosed herein connected to a command and report computer and to a wireless access point under test;
- FIG. 2 is a block diagram illustrating the internal functional elements of the load emulator and the connections of the load emulator to the command and report computer and to the access point under test, and
- FIG. 3 is a flow diagram illustrating the operations of the load emulator functional elements along with load emulator command and report computer interaction.
- Referring now the drawings, a representative wireless access point test environment embodying the principles of the present invention and utilizing a load emulator is depicted in FIG. 1 and identified by
reference character 20. In this system command and reportcomputer 22 is connected by a serial wiredconnection 23 called a command line interface (CLI) to aload emulator 24 also encompassing those principles. The load emulator is connected over awireless radio link 26 conforming to the 802.11 standard to anaccess point 24 under test. The access point is typically, but not necessarily, wired into a traditionalenterprise data network 28. - The functional elements of the novel and
representative load emulator 24 are depicted in FIG. 2. These are: acontroller 30 for command/report computer 22, avirtual station processor 32, access point input/output controller 34, and a log andstatistics file 36. -
System 20 is readied by initializingload emulator 24. To initialize the load emulator, a body of virtual station parameters is entered into command and reportcomputer 22 either manually, or from a table of parameters stored in that computer. This station profile block of information contains a media access control (MAC) address, Internet protocol (IP) address, a station name and password, and packetized data for the transmission to the access points being tested. The MAC and IP addresses are specified over a range which accommodates the desired number of virtual stations. Packet sizes are specified over an allowable range, and are unique for each virtual station, thus realistically emulating a typical station population. - The
virtual station processor 32 is responsible for execution of thetest scripts 34, performing initial access point authentication through the input/output controller 34, the calculation of elapsed time, the recording of success or failure conditions, and the logging of the information into the log andstatistics file 36. With successful authentication based on a virtual station name and password, thevirtual station processor 32 initiates anassociation procedure 44 through the input/output controller 34. The input/output controller communicates directly with theaccess point 28 under test over 802.11wireless link 26. Virtual station association elapsed time is calculated, success or failure recorded and resulting information loaded into log andstatistics file 36. With successful authentication and association processes completed,virtual station processor 32 transfers a packet of realistic data to the input/output controller 34 for transmission over the wireless 802.11link 26 to theaccess point 38 under test. Elapsed time and throughput of the data transfer is calculated with resulting data being stored in the log andstatistics file 36. - This process is repeated in sequence for each virtual station until completion of the test run. At the conclusion of the
test run controller 30 causes test data to be exported from log andstatistics file 36 to command and reportcomputer 22 for analysis of the recorded data and display of test results. - FIG. 3 depicts internal operations of the
load simulator 24, beginning with stationblock initialization process 38 and station profileblock definition process 40 by the external command and reportcomputer 22. Inload emulator 24 the station profile block 41 is loaded with a MAC address, an IP address, and packetized data for transmission. Arepeat loading process 42 tracks the number of virtual stations to be tested and determines when the last station has been emulated. Once all virtual station profile blocks have been loaded, activevirtual station process 44 is enabled. A virtual station name and password are passed to input/output controller 34 and presented to theaccess point 28 under test for authentication of the particular virtual station. Elapsed time and success or failure of the virtual station authentication is stored in log andstatistics file 36. Upon successful authentication virtual station association is attempted by the initiate/end association process 46. Elapsed time and success or failure of the virtual station association is stored in log andstatistics file 36. - With successful authentication and association of the virtual station, a programmable sized packet of data is transferred to the input/
output controller 34 for transmission over the 802.11wireless link 26 to theaccess point 28 being tested (process 47). Elapsed time of the data transfer is calculated, error conditions reported and data throughput recorded in log andstatistics file 36. - A
second repeat process 48 sequentially processes all virtual stations, one after the other, by triggering activatevirtual station process 43 until the last virtual station has been emulated. Upon completion of the test run, therepeat loading process 48 signals completion to log andstatistics file 36. The log and statistics file information is then transferred by exportlog file process 50 acrossCLI 23 to the command and reportcomputer 22, which analyzes the information (process 52), and displays the results (process 54). - The invention may be embodied in many forms in addition to those disclosed herein without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
